Read the second part of the text «The Properties of Electromagnetic Waves» and give the definitions of the phenomena describing in the text by your own words:
In everyday life, each of us daily faces reflection. For example, sometimes, in order for a mobile phone to lose contact with a base station, it is enough to enter a room with thick reinforced concrete walls or even an ordinary house elevator. Returning to the experiment: if you place the generator and receiver at an angle to each other, the signal will not be recorded (directional emitter). But it is worth placing at the intersection point of two conditional lines (directional vectors) a plate of metal, as the receiver will catch radiation, that is reflection. Similar properties of electromagnetic waves are formulated in the statement about the equality of the angles of incidence and reflection.
The next property is refraction. If the receiver and the directional emitter are located at different heights, the signal will not be caught. But if you put a paraffin cube between them, the whole scheme works. This is due to a change in the direction of wave propagation at the boundary of two dielectric media (paraffin and air).
Next worth mentioning is interference. If two metal plates are placed in close proximity to each other, forming an angle slightly smaller than 180 degrees, then when the radio wave is emitted to these sheets, the receiver will perceive a difference in their intensity, depending on its placement relative to the sheets. A well-known example is a satellite dish. It is the "plate" that amplifies the signal, collecting scattered waves and concentrating them on the receiver.
Another well-known property is diffraction. Partially it enables to use radio receivers. The experiment is as follows: between the generator and the receiver we put a metal plate, and, the distance between them is minimal. As a result, the signal is absent, since it is reflected from the plate back, towards the generator. But if you spread the generator and receiver away from the plate, the signal will appear. This is due to the property of waves to envelop obstacles.
